5(4c−2d)+2d−6(d−3c). Distribute: =(5)(4c)+(5)(−2d)+2d+(−6)(d)+(−6)(−3c) =20c+−10d+2d+−6d+18c. Combine Like Terms: =20c+−10d+2d+−6d+18c =(20c+18c)+(−10d+2d+−6d) =38c+−14d.

Hi

5(4c-2d) + 2d - 6(d-3c) = 20c - 10d + 2d - 6d + 18c

5(4c-2d) = 5(4c)+5(-2d) = 20c-10d
- 6(d-3c) = -6(d)-6(-3c) = -6d+18c

20c - 10d + 2d - 6d + 18c = 20c + 18c - 10d - 6d + 2d = 38c - 14d

20c+18c = 38c
-10d-6d+2d = -16d+2d = -14d

Answer: 38c-14d

Solve the following system by any method -8x-8y=0 -8x+2y=-20

iVinArrow [24]

$\fbox{Solution by using Matrix}$

$\text{Linear Equation} = -8x-8y=0 , -8x+2y=-20$

$\text{Rewrite the linear equations above as a matrix}$

$\left[\begin{array}{ccc}8&-8&0\\-8&2&-20\\\end{array}\right]$

$\text{Apply to Row2 : Row2 + Row1}$

$\left[\begin{array}{ccc}8&-8&0\\-8&-6&-20\\\end{array}\right]$

$\text{ Simplify rows}$

$\left[\begin{array}{ccc}8&-8&0\\0&1&10/3\\\end{array}\right]$

$\text{Note: The matrix is now in echelon form.}$ $\text{The steps below are for back substitution.}$

$\text{Apply to Row1 : Row1 + 8 Row2}$

$\left[\begin{array}{ccc}8&0&80/30\\0&1&10/3\\\end{array}\right]$

$\text{ Simplify rows}$

$\left[\begin{array}{ccc}1&0&10/3\\0&1&10/3\\\end{array}\right]$

$\text{Therefore, the solution is}$

$x= \dfrac{10}{3} \ \text{and} \ \ y=\dfrac{10}{3}$
